How to fix problem with sendJsonRequest promise in connectdialog.js?

Thu, 11 Jun 2015 05:02:11 GMT

I've made several little changes in my connector and now it can't send JsonRequest to server.

$scope.onTestConnectionClicked = function () {

console.log("testConnection init");

var promise = input.serverside.sendJsonRequest("testConnection", $scope.username, $scope.password);

console.log(promise);

console.log("testConnection promise generated");

promise.catch(function(a) {

console.log("Catched ex");

console.log(a);

});

promise.then( function ( info ) {

$scope.connectionInfo = info.qMessage;

$scope.connectionSuccessful = info.qMessage.indexOf( "OK" ) !== -1;

} );

};

Error I get, when onTestConnectionCliked function fires:

Error from Engine: Object {jsonrpc: "2.0", id: 51, error: Object}

Error object: code: -1 message: "Unknown error" parameter: "General exception"

My HandleJsonRequest method, from class QvAmoCrmServer (extends QvxServer)

(Two implementations, same effect)

First one:

public override string HandleJsonRequest(string method, string[] userParameters, QvxConnection connection)

{

QvDataContractResponse response;

QvxLog.Log(QvxLogFacility.Application, QvxLogSeverity.Debug, "Handle json Request > " + method);

string provider, host, username, password;

connection.MParameters.TryGetValue("provider", out provider); // Set to the name of the connector by QlikView Engine

connection.MParameters.TryGetValue("userid", out username); // Set when creating new connection or from inside the QlikView Management Console (QMC)

connection.MParameters.TryGetValue("password", out password); // Same as for username

connection.MParameters.TryGetValue("host", out host); // Defined when calling createNewConnection in connectdialog.js

switch (method)

{

case "getInfo":

response = getInfo();

break;

case "getDatabases":

response = getDatabases(username, password);

break;

case "getTables":

response = getTables(username, password, connection, userParameters[0], userParameters[1]);

break;

case "getFields":

response = getFields(username, password, connection, userParameters[0], userParameters[1], userParameters[2]);

break;

case "testConnection":

response = testConnection(userParameters[0], userParameters[1]);

break;

default:

response = new Info { qMessage = "Unknown command" };

break;

}

return ToJson(response); // serializes response into JSON string

}

And another:

public override string HandleJsonRequest(string method, string[] userParameters, QvxConnection connection)

{

return JsonConvert.SerializeObject(new Info {qMessage = "Test response"});

}

Method HandleJsonRequest didn't call at all.

First implementation executes Log method, but log is empty.

Hey,

Have you solved the sendJsonRequest-problem?

If yes, can you give me an advice? I am facing a similar issue and have no idea which mistake I made that I get this error.

Thanks in advance!
